Choose the right adapter for your needs — from basic code reading to as-built read & compare. ScanFixAI supports ELM327 for diagnostics and J2534 pass-through for reading and backing up Ford module configuration, with guided module writes rolling out in preview, verified per-vehicle on a real car.
Your adapter determines what ScanFixAI can do. Basic adapters handle diagnostics. J2534-capable adapters unlock as-built read & compare and module config backup & read, with guided writes (module programming, SYNC updates, calibration flashing) rolling out in preview, verified per-vehicle on a real car.
The best all-around adapter for Android and Windows. Bluetooth connectivity with J2534 pass-through capability for ECU programming (guided write in preview). Fast, reliable, and works wirelessly.
The go-to adapter for serious Ford work. USB connection with full J2534 + FEPS support for all Ford module programming, including older PCMs that require battery voltage simulation. Also supports Ford MS-CAN (medium-speed CAN bus).
Good enough for basic diagnostics: reading and clearing codes, live data, and AI-powered diagnosis. No programming capability. Stick with reputable brands to avoid connection issues with cheap clones.

ScanFixAI reads and backs up as-built configuration across 21 Ford modules using J2534 pass-through. Guided module writes — flashing new calibrations, applying TSB fixes, updating SYNC, and reprogramming modules after replacement — are rolling out in preview, verified per-vehicle on a real car.
Engine calibration updates, TSB performance fixes, emissions strategy updates, and idle quality improvements. The most commonly reflashed module.
Transmission shift strategy updates, torque converter shudder fixes (common on 6F35/6R80), and adaptive learning resets after rebuild.
Update SYNC 1, 2, 3, or 4 to the latest software. Add navigation maps, fix touchscreen bugs, enable new features. Covers all Ford, Lincoln, and Mercury SYNC-equipped vehicles.
Reprogram instrument cluster after replacement, update gauge firmware, configure chime settings and display options.
Lighting configuration, remote start setup, door lock behavior, perimeter alarm settings, and accessory delay programming.
Brake system calibration updates, stability control recalibration, and TSB-related software fixes for ABS pump and sensor issues.
Airbag system updates, crash data clearing after deployment, and occupant classification calibration. Required after any airbag module replacement.
ADAS front camera calibration after windshield replacement. Required for lane keeping, adaptive cruise, and pre-collision assist to function correctly.
Hybrid and EV battery management programming. Supports Mach-E, F-150 Lightning, Escape Hybrid, and Fusion Hybrid. Critical for battery pack balancing and charging strategy updates.
Electric power steering calibration, steering assist curve adjustments, and torque sensor recalibration after module replacement.
Amplifier and audio system firmware. Required when upgrading audio systems or replacing the ACM after failure.
Central network gateway programming. The GWM routes communication between CAN buses — must be updated when adding or replacing networked modules.
High-voltage to 12V converter programming for hybrid and EV platforms. Controls auxiliary battery charging and power distribution.
Additional emissions monitoring module found on 2018+ vehicles. Handles OBD-II readiness and emissions compliance.
Climate system programming, blend door actuator calibration, and dual-zone sync configuration.
Window, lock, and mirror control programming. Required after door module replacement to restore one-touch and memory features.
Same as PDM for the driver side. Controls window express, mirror fold, and seat memory triggers.
Navigation module firmware and map data updates. Separate from APIM on vehicles with dedicated nav units.
FordPass Connect and modem programming. Handles remote start, vehicle status, and over-the-air update connectivity.
Steering column controls, paddle shifters, and multifunction switch programming. Required after clockspring or column replacement.
Parking sensor calibration, active park assist programming, and sensor zone configuration after bumper work.
Gather these items before starting any guided module programming session (rolling out in preview).
